Most folk miss out on a free 3 month warranty extension. I can't tell what country this is in but if in the USA head to samsung.com and register it to get the 3 extra months and pull it back into warranty.
I have a Samsung LCD (LA37A450C1D) that is just out of warranty that has started displaying a very dark/ dimmed picture. The only way you can watch anything is to crank up the backlight and contrast settings, but even then the image is not good. Don't think it's a capacitor problem as they all look ok, and I assume if the backlight was totally broke then it wouldn't display anything at all? Anyone have any suggestions for a fix? Not worth me spending the money for an out of warranty repair, as a new TV would be almost as cheap...
